Abstract2D transition metal borides (MBenes) have garnered significant attention from researchers due to their exceptional electrical conductivity, strong mechanical rigidity, excellent dynamic and thermodynamic stability, which stimulates the enthusiasm of researchers for the study of MBenes. Over the past few years, extensive research efforts have been dedicated to the study of MBenes, resulting in a growing number of synthesis methods being developed. However, there remains a scarcity of comprehensive reviews on MBenes, particularly in relation to the synthesis techniques employed. To address this gap, this review aims to provide a comprehensive summary of the latest research findings on MBenes. An exhaustive exploration of the crystal structure types of MBenes is presented, highlighting the greater structural diversity compared to MXenes. Furthermore, a comprehensive review of the recent advancements in MBenes synthesis methodologies is provided. The review also delves into the physical and chemical properties of MBenes, while elucidating their applications in the realms of energy conversion and energy storage. Lastly, this review concludes by summarizing and offering insights on MBenes from three angles: synthesis, structure‐property relationships, and application prospects.

The advancement of dye-sensitized solar cells (DSSCs) critically hinges on the innovation of cost-effective, high-performance counter electrode (CE) catalysts. This research outlines a synthesis route for fabricating platinum (Pt)-free CE catalysts, specifically alkalized Ti 3 C 2 T x MXene−PEDOT nanofibers (a-Ti 3 C 2 T x -PNFs). The synthesis methodology entails the alkalization of acid-etched Ti 3 C 2 T x using KOH, followed by intercalation with PEDOT nanofibers. The formation of the hybrid a-Ti 3 C 2 T x -PNFs was confirmed through an array of characterization techniques, including XRD, XPS, HRSEM, and HRTEM. Electrochemical evaluations revealed that the a-Ti 3 C 2 T x -PNF hybrid exhibits exceptional catalytic reduction capabilities and demonstrates a remarkably low chargetransfer resistance of 8.5 Ω cm 2 for the reduction of triiodide electrolyte. Consequently, DSSCs incorporating the a-Ti 3 C 2 T x -PNF CE achieved a power conversion efficiency (PCE) of 7.1% under optimized conditions, closely approaching the 8.06% efficiency observed with Pt-based CEs. Moreover, the reproducibility and stability tests confirmed that the a-Ti 3 C 2 T x -PNF CE offers consistent performance and high corrosion resistance in iodide/triiodide electrolyte. These findings emphasize the possibility of using a-Ti 3 C 2 T x -PNFs as a practical substitute for platinum in high-performance DSSCs, representing a notable advancement in the progress of contemporary solar cell technology.
